what transition metal complex is responsible for transporting oxygen in our blood? Also, what is its structure?
The transition metal (there are several transition series---I assume you are referring to the 3d transition metals) is iron. As to its sturcure, the iron itself has no structure other than its electronic structure. It is the metal in hemoglobin.I will try to find the structure of the complex on the net and post it later.
Here is the structure of hemoglobin.

The transition metal complex responsible for transporting oxygen in our blood is iron (Fe). In the case of oxygen transport, the iron is found in the heme group of hemoglobin, a protein in red blood cells.
To determine the structure of the iron complex in hemoglobin, you can research it further, such as looking at scientific articles or books on biochemistry. However, as an AI, I can provide a brief description of the structure.
Hemoglobin is composed of four subunits, each containing a heme group. Each heme group consists of a porphyrin ring with an iron atom at the center. The iron atom can form coordination bonds with various ligands, including oxygen.
The oxygen molecule binds to the iron in a reversible manner. When oxygen is bound to the iron, the complex is called oxyhemoglobin. This allows oxygen to be transported from the lungs to the body tissues. When oxygen is released from the iron, the complex is called deoxyhemoglobin.
Overall, the structure of the iron complex in hemoglobin is critical for its function in oxygen transport in the human body.
